Conclusions • It seems to be possible to compare transparent and opaque colours • The pilot indicates that a computer screen could be used • NCS can be used and expanded to the chromatic area
Questions for the future • What kind of tool do designer/artists and producers need? • How does thickness and shape affect the colour experience? • What are the technical prerequisites for using a computer screen?
